After promising several people late last year that I would make them a sparge/wort aerator head, I have finally managed to get some time to make them – apologies for the long wait ­čÖü

I’ve made a few of them, one to fit 10mm pipe and one to fit 15mm pipe. ┬áPreviously the 10mm pipe size was the preferred choice – possibly because it was easy to get 10mm stainless tube but I am not actually sure.

I came across an open source flight controller project designed for Quadcopters called Simple Flight Controller (SFC) which is based on an MSP430 – specifically the RF2500 2.4GHz development modules. I modified the source to compile on MSPGCC and got it to say “hello world” to me but then had to shelve it due to pressing work projects.
